1. Archiving Techniques Frank Klaproth EMANI – Project Meeting February 14 th - 16 th, 2002 Springer-Verlag Heidelberg Göttingen State and University Library (SUB) emani@mail.sub.uni-goettingen.de

2. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen General Remarks, Definition  What is archiving?  hold a: Digital copy, digital version, part of the digital original  make permanent accessible  „transport“ digital information lossless

3. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen The Situation at Göttingen...  Using ADSM/TSM with HSM for archiving digitized materials (math journals, travel literature, spec. collections) in the GDZ  Cooperation with University Computer Center (GWDG)

4. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen...  25 TB

5. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen...  Cooperation with GWDG / MRZ / VZG / SUB / MPG  Planned 2nd Data archive with 200 TB (up to 5.500 TB)  Testing LOCKSS

6. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen Environment - Hardware  processing units  x86, VC20, MIPS, RISC,...  storage media  RO hardware (CD ROM, DVD)  RW hardware (CDRW, hard disk, floppy, tape,...)

7. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen Environment - Software  Operating Systems  Unix ( AIX, SiNIX, Solaris, Linux, FreeBSD,...)  MS DOS, MS WinX,...  MAC OS,...  CPM  Applications  Text-, Graphic, Multimedia production tools  Reader, Presentation tools

8. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen Methods - Migration  Reasons for migration  Minimize variety  Time  („end of live“ of hard- and software)  emerging standards  Using standards makes migration possible  Different document formats and different hardware environments

9. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen Methods - Emulation  emulation can follow migration  example: data on floppy disk migrates into a online storage medium (hard disk)  software can be emulated in a processing unit environment which handels data format from migrated floppy disk  VMWare (runs on Unix, MS WinX, MAC)  multiple OS with multiple software environments on one hardware environment

10. February 14 th - 16 th, 2002 EMANI Project Meeting SUB Göttingen Other  access  handling and using URNs, persistent identifiers  signatures for documents  signatures for service /server provider  Trust Center
